2 Claims. (Cl. 128-251) This invention relates to an improved douche syringe and more particularly to a douche syringe used in the human vagina.

An object of the present invention is to provide means for making pleasant, repeated and .thorough injections of a current of water or other fluid into the human vagina.

Another object of this invention is to provide a douche syringe which can be easily and painlessly inserted into and withdrawn from the human vagina.

A further object of this invention is to provide a douche syringe which can be withdrawn from the human vagina without producing a painful drainage of mucus therefrom.

A still further object of this invention is to provide a sanitary douche syringe which is of simple construction, marketable at a comparatively inexpensive price and which will Withstand prolonged usage.

In the accompanying drawings,

Figure 1 is a side elevation of one form of a douche syringe embodying the invention;

Figure 2 is a longitudinal sectional view of the douche syringe indicated in Figure 1.

Referring in detail to the drawings, the embodiment of the invention therein shown is a complete vaginal douche syringe comprising a relatively hard vaginal nozzle 1, one end of which is secured within a resilient flexible seal 2 constructed of a material such as ordinary rubber and adapted to prevent soiling or wetting of surrounding objects when the said nozzle 1 is inserted within the vaginal canal. The latter end of the vaginal nozzle 1 also secures a small, substantially rigid check valve casing which may be constructed of hard rubber and which projects axially from within the end of the said nozzle 1 into the interior of a collapsible, resilient rubber bulb 3 capable of holding, when inflated, a quantity of water or other fluid intended for injection into the vaginal canal. The aforesaid check valve casing 5 contains a check valve 7 for allowing the passage of the said water or fluid into the vaginal nozzle 1 but the said valve 7 is located so as to prevent any substantial quantity thereof to pass in a reverse direction from the said nozzle 1 into the said bulb 3. The check valve 7 may be composed of soft rubber or other substantially firm material and may be formed in the shape of a small cylinder or ball capable of resting on the raised annular shoulder which appears at one end of the said check valve casing 5; and can be retained within the interior thereof by a substantially rigid retaining pin 9 inserted through the side walls of the said casing 5 so as to prevent the exit of the said valve 7 from the said casing 5. .A similar check valve casing 6 containing a similar check valve 8 and a similar retaining pin is aflixed within the opposite end of the bulb 3 and projects axially into the interior of a suction tube 4 containing a number of perforations at one end thereof suificient to facilitate the passage of air, water or other fluid from an outside source (not shown) into the interior of the said suction tube 4. In the case of the check valve 8, however, it should be noted that it is located so as to allow the passage of water, air or other itgfi States Patent 9 F 2,748,770 Patented June 5, 1956 fluid from the suction tube 4 into the interior of the bulb 3 but does not allow the saidsubstances to pass in any substantial quantity in a reverse direction from the said bulb 3 to the interior of the said tube 4.

To operate the vaginal douche syringe hereinabove set forth it is first necessary to collapse by means of manual pressure the resilient bulb 3 thus exhausting through the vaginal nozzle 1 any undesirable contents held within the said bulb 3 and at the same time exhausting the air therefrom so as to create a partial vacuum therein. The suction tube 4 is then inserted within a source of douching substance such as a quantity of water or other fluid whereupon the manual pressure exerted upon the bulb 3 is released so as to allow the said bulb 3 to expand and draw into itself a substantial quantity of the said water or fluid through the interior of the suction tube 4, the check valve casing 6 and past the check valve 8. During the latter expansion of the said bulb 3 no substantial quantity of air or other fluid substance may enter the said bulb 3 from the vaginal nozzle 1 because the decrease in pressure within the said bulb 3 will effect a substantial closing of the check valve '7 by forcing same against the annular shoulder contained within the check valve casing 5. When the desired quantity of douching substance has been drawn into the bulb 3, the vaginal douche syringe is withdrawn from the source of douching substance and the vaginal nozzle 1 is inserted slowly and comfortably into the human vaginal canal to a position whereby the vaginal opening is covered by the resilient, flexible seal 2 so as to prevent liquid drainage from the surrounding vaginal canal. The douching substance can then be applied as desired simply by compressing the bulb 3 and forcing the said douching substance through the check valve casing 5 beyond the check valve 7 contained therein into the vaginal nozzle 1 and from there to the surfaces of the vaginal canal. When the latter pressure is exerted, it should be noted that it is transmitted by the contents of the bulb 3 to the check valve 8 so as to move the said check valve 8 to a position against the annular shoulder of the check valve casing 6 thereby closing the said casing 6 and preventing the passage of the contents of the bulb 3 into the suction tube 4. At the same time the said pressure acts upon the check valve 7 so as to force it away from the annular shoulder of the check valve casing 5 thus maintaining an open passageway between the interior of the said bulb 3 and the interior of the said vaginal nozzle 1.

When the current of douching substance has been injected into' the vaginal canal the pressure upon the bulb 3 is again released thus allowing the said bulb 3 to assume its inflated shape. In this instance no substantial quantity of douching substance, mucus or other material will be withdrawn from the vaginal canal because the partial vacuum created by the expansion of the bulb 3 will be dissipated and relieved by the passage of air into the suction tube 4 through the check valve casing 6 past the check valve 8, which will be moved away from the annular shoulder of the said casing 6 and into an open position, and into the interior of the bulb 3, thus diminishing any tendency to Wash back into the syringe the said douching substance, mucus or other material. Furthermore this tendency will be reduced by the action of the check valve 7 which will be forced by the passage of any of such substances against the annular shoulder of the check valve casing 5 thus substantially closing same. Since the forced withdrawal of mucus from the vaginal area may be a source of much pain and discomfort, the elimination of this tendency by means of the present invention is notable.

In the event that the entire quantity of douching fluid contained within the bulb 3 has not been used in the douching operation set forth above, the said fluid can be further applied to the surfaces of the vaginal canal by again compressing the bulb 3. This procedure may be repeated as desired. Thereafter the douche syringe can be easily withdrawn from the vaginal canal. This action will be facilitated by the passage of air into the suction tube 4 through the check valve casing 6 past the check valve 8 through the bulb 3 past the check valve 7 through the check valve casing into the vaginal nozzle 1 and from there to the vaginal area, the said passage of air being induced by any decrease in pressure arising in the vaginal canal as a result of the withdrawal of the said douche syringe. This entry of air thus prevents any painful withdrawal of mucus from the vaginal canal as well as any painful pulling upon the adjacent vaginal tissues by the vaginal nozzle 1 which might otherwise arise in the event of the said decrease in pressure.

The douching procedure above described may be repeated in its entirety as frequently as desired.

The embodiments of the invention illustrated and described hereinabove have been selected for the purpose of clearly setting forth the principles involved. It will be apparent, however, that the present invention is susceptible of being modified in respect to details of construction, combination and arrangement of parts which may be resorted to without departure from the spirit and scope of the invention as claimed.
